multicomp
Dear R people,
I have heard rumors of a function called (I believe) multicomp in S+ for
doing multiple comparisons for linear models. It doesn't seem to be in the
version of R I am using, 0.90.0. Is there something equivalent to this in
R, or does it simply not exist?
I see there is are more recent versions of R. For my platform, SuSE Linux,
the most recent rpm available appears to be

Multiple comparisons in R; multicomp
Is there a fonction for multiple comparison tests (similar to "multicomp" in Splus) in a package of R?
Thanks in advance for any hint...

How to use lmer function and multicomp package?
Dear list members,
First of all thank you for your helpful advices.
After your answeres to my firt mail I studied a lot (R-News n?5) and I
tried to perform my analysis:
First, to fit a GLM with a nested design I decided to use the function
"lmer" in package "lme4"
as suggested by Spencer Graves and Filippo Piro.
I remember to you that my data were:

multcomp and lme
I suppose that multcomp in R and multicomp in S-Plus are related and it
appears that it is possible to use multicomp with lme in S-Plus given the
following correspondence on s-news

Question about command "multicomp"
Dear R-People
I did some two way variance analysis and have now the following problem:
I''d like to do some multiple Comparisons between different factor levels
(two factors, each with some 5 or 6 levels), because there are some
significant interactions between these two factors.
In S-plus 5, there is the function "multicomp", but in R, there ist no
matchable funktion, as far

Which function to use for multiple comparison?
[Moderator: This was erronously sent to R-announce,
and filtered fortunately ]
Hi,
This is my first time to use R. I'm wondering which function I can use to do
multiple comparison. I have an lm object and want to do multiple comparison
based on this object. Splus has a function multicomp() but I could not find
a similar one in R. Thanks in advance. Really appreciate it.

Point labels
Hello,
Is there an option I can easily set to put labels next to the points in a
simple plot?
The closest I got to it was to use the option pch, but this replaces the
point symbol with the character specified, and it is not what I want.
Thanks

multiple comparisons
I'm having trouble finding an R equivalent to the S-Plus "multicomp"
function, which does post-hoc comparisons of treatments means in
ANOVAs. Am I missing something obvious?
Thanks, Peter

multcomp, simint, simtest and computation duration
Dear R-listers,
I am trying to compute simultaneous confidence intervals with simint from the package multcomp. 230 measures (abundance) have been taken in 23 sites (factor) of a data.frame (donnees: a file can be sent on request, saved with save(donnees,file="donnees")). I would like to get all pairwise comparisons with :

writing complex outputs to table
So I've come across a few cases where complex outputs from functions
will not write to tables. The most recent case involves the TukeyHSD
function in the stats package. If I save the TukeyHSD call and print it,
that obviously goes fine, but when I try writing to a table, I get an
error message that says "cannot coerce class \multicomp\" into
dataframe. What does this mean, and

LME and overall treatment effects
Hello fellow R users,
I am having a problem finding the estimates for some overall treatment
effects for my mixed models using 'lme' (package nlme). I hope someone
can help.
Firstly then, the model:
The data: Plant biomass (log transformed)
Fixed Factors: Treatment(x3 Dry, Wet, Control) Year(x8 2002-2009)
Random Factors: 5 plots per treatment, 5 quadrats per plot (N=594 (3*5*5*8)

I have some experimental data where I have counts of the number of

C, D] were applied to the traps (variable - semio) and all were

External MWI question for Asterisk
Hey there. I've been working on a project to integrate Asterisk with
Exchange Unified Messaging via sipX using large parts borrowed from:

... and everything works surprisingly well. The one problem I have is MWI,
or a lack thereof. Exchange 2007 doesn't support MWI of any kind (!), so

Use of all/any
all/any coerce their arguments to logical (if possible). I've added a
warning in R-devel if coercion is from something other than integer.
This arose because it is easy to make a slip and write all(X) > 0 rather
than all(X > 0): thanks to Bill Dunlap for bringing that to my attention.
However, it has been useful in detecting quite a few other things:

points(*, pch=NA) does *not* not draw the point (PR#6876)
We say in ?points that 'pch' (among others) can be set to NA
for omitting a point.
While this works in cases where there's at least one point left
to draw, it fails in a simple case like this :
> plot(1, pch = NA)
Error in plot.xy(xy.coords(x, y), type = type, pch = pch, col = col, bg = bg, :

This only happens if 'file' is a text connection, and is the expected
behaviour in that case: you cannot capture an incomplete line to a text
connection.
There seems no reason to break the documented behaviour in other cases to
change something that you consider to a bug when file=NULL and the user
does not produce complete output. It would be possible to make use of
